SF6 Density Relay Calibration Tester
IntroductionSF6 gas density relay is an important component used to monitor the change of SF6 gas density in the SF6 switch body during operation. Due to the infrequent action of SF6 gas density relay in field operation, it often has inflexible action, poor contact and other phenomena after a period of time, and some also show that the temperature compensation performance of density relay becomes worse, Sudden change of ambient temperature often leads to misoperation of SF6 density relay. Therefore, DL / T596-1996 preventive test code for power equipment stipulates that each SF6 switch user shall regularly calibrate the SF6 gas density relay. RNSFJ SF6 density relay calibrator is developed according to DL / t259-2012: Calibration Specification for SF6 density relay issued by the national energy administration.
